Observation Tips Strictly nocturnal, unobtrusive habits, and retiring nature, make this a difficult species to find. Best chances come from learning the vocalizations and tracking down a calling bird after dark with the aid of a powerful flashlight; beware, however, Flammulateds are good ventriloquists, so this is not an easy task. Otherwise, befriend a birder who knows the species well. Almost impossible to find when not calling.
